Description
Technical field
This utility model relates to plunger pump technique field, particularly relates to a kind of hydraulic control valve.
Background technology
At present, the hydraulic control valve that axial plunger pump is used, it is desirable to have root high-voltage tube is connected in the cavity of valve body at the oil-out of valve body.Because many root high-pressure oil pipes, considerably increase cost, also increase hydraulic oil leak point, improve the difficulty of plant maintenance personnel, for this reason, it may be necessary to optimize the structure of hydraulic control valve.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of hydraulic control valve, spool design inside hydraulic control valve goes out into through hole shape, thus reaches to cause hydraulic oil in the cavity of valve body, decreases hydraulic oil leak point, greatly reduce equipment cost simultaneously, facilitate plant maintenance.
This utility model solves its technical problem and be the technical scheme is that a kind of hydraulic control valve of offer, including valve body, oil-in and spool, pipeline is laterally had in described valve body, it is slidably fitted with spool in this pipeline, described pipeline one end is connected with oil-in, this pipeline other end is connected with cavity, passage is had in the middle part of described cavity, in this cavity, spring is installed, one end of described spring is fixed with cavity, the other end of this spring is connected with spool, described spool laterally has through hole, one end of this through hole communicates with oil-in, the described through hole other end communicates with cavity.
Supplement as to the one of technical scheme described in the utility model, one end that described spool is connected with spring has two bifurcated passages, one end of this bifurcated passage communicates with cavity, and the other end of described bifurcated passage communicates with through hole, by the cavity of dispersed for hydraulic oil introducing valve body.
Supplementing as to the one of technical scheme described in the utility model, be provided with plug screw on the right side of described valve body, this plug screw one end is connected with spring one end in extending into cavity.
Supplement as to the one of technical scheme described in the utility model, be connected with several oil-outs in the middle part of described pipeline.
Supplementing as to the one of technical scheme described in the utility model, described spool vertically has shunt conduit.
Beneficial effect
This utility model relates to a kind of hydraulic control valve, and the spool design inside hydraulic control valve goes out into through hole shape, thus reaches to cause hydraulic oil in the cavity of valve body, decreases hydraulic oil leak point, greatly reduces equipment cost simultaneously, facilitate plant maintenance.
